2003-07-18  Nick Garnett  <[e-mail]>

	* cdl/hal_mips_vr4300_vrc4373.cdl:
        Changed values for CYGNUM_HAL_RTC_NUMERATOR,
        CYGNUM_HAL_RTC_DENOMINATOR and CYGNUM_HAL_RTC_PERIOD to
        "default_value" from "calculated". This makes it easier
        to change these values globally.

1999-11-02  Jesper Skov  <[e-mail]>

	* cdl/hal_mips_vr4300_vrc4373.cdl: Added.

1999-10-29  Nick Garnett  <[e-mail]>

	* include/plf_intr.h: 
	* src/plf_misc.c:

	of the 32 bit word in big endian mode.

	* include/plf_z8530.h: In big-endian mode the Z8530 registers are
	at the other end of the word. This is easily fixed by redefining
	the DUART_BASE only.

	control the above behaviour

1999-09-08  Jonathan Larmour  <[e-mail]>

	* include/plf_intr.h (HAL_INTERRUPT_UNMASK): Rephrase to silence warnings
	about left-shifting negative numbers. Equivalent when optimized.
	(HAL_INTERRUPT_ACKNOWLEDGE): Likewise
	(HAL_INTERRUPT_MASK): Likewise

1999-09-09  Nick Garnett  <[e-mail]>

	* include/platform.inc: Changed end address for copy from
	__bss_end to __ram_data_end.

	* src/platform.S (NTLBENTRIES): Fix typo: 0x32 -> 32

	* include/platform.inc (hal_mon_copy_trampoline): Use branch delay slot
	when copying - both for ROMRAM startup and CYG_HAL_USE_ROM_MONITOR_PMON
	(hal_mon_init_vsr_table): Don't init debug vector - not used on
	vr4300 CPUs

1999-09-02  Nick Garnett  <[e-mail]>

	* include/platform.inc: Added code to monitor setup to copy
	other_vector in to correct RAM location.

1999-08-19  Nick Garnett  <[e-mail]>

	* include/plf_io.h: Added this file to contain PCI access support.

	* include/platform.inc:
	* src/platform.S: 
	Added function to read data from the PCI data register together
	with a data load/store VSR which catches any exceptions and fixes
	them up so that the program can continue.

1999-07-15  Jonathan Larmour  <[e-mail]>

	* src/hal_diag.c: Add prototypes for cyg_hal_is_break and
	cyg_hal_user_break to silence warning

1999-06-21  Nick Garnett  <[e-mail]>

	* src/plf_misc.c (hal_ctrlc_isr): Changed all return codes to 2 so
	that the interrupt is reported as handled.
